SPECIFICATION forming part of Letters Patent No. 606,066, dated June 21,1898. Application filed April 2i, is'ev. sei'iurofe'eaist. '(NomodelJToaZZ whom it may concern.- Be it known that we, JOSEPH A. LONG andLOWMAN HAwns Lone, citizens of the United States, residing at Brooklyn,in the county of Kings and State of New York, have invented anImprovement in Oar-Heaters, of which the following is a specification.

The object of the present invention is to provide a heater especiallyadapted to the cars upon city railways wherein there is no opportunityto obtain steam heat, as from a' locomotive, and in which the spacesometimes occupied by a stove is valuable.

In the present invention the heater is placed beneath the seat and isadapted to warm the car without lesseningthe space provided for thepassengers, and two or more heaters may be provided in the same car,especially in those cars of large dimensions.

Artificial fuels are known and in use which smoulder or burn withoutflame or smoke and which give out a considerable'heat and do not burn uprapidly. The present invention is adapted to artificial fuels of thischaracter, and it may also be used with charcoal or other fuel thatburns slowly and does not produce smoke.

\Ve provide a fire-pot with a tight cover at the upper end, by theremoval of which the fuel can be inserted into the fire-pot, and withinthe fire-pot there is a removable basket of Woven wire or similarmaterial, into which the fuel is insertedand it is consumed gradually,and at the bottom of the fire-potth'ere is an ash-drawerinto which anyearthy materials may be received and into which an inflammable torch isinserted for igniting the f uel,and there are openings in the lower partof the fire-pot,through which air is admitted and through which anywaste products of combus tion, such as carbonic acid, may pass away, andaround the fireepot is a casing into which air is allowed to pass fromthe bottom, so as to become heated, and a sheet-metal box surrounds thecasing and fire-pot and is adapted to set beneath the car-seat and toopen through the floor, and there are lateral openings for the escape ofthe warm air from this box into the car. The whole apparatus is portableand can be easily placed in the car or removed therefrom, and when thecar is laid up at night the fuel can be lifted outfrom the firepot bythe open-work basket, so as to be who tied or tobe used in some othercar, thereby avoiding the risk of fire even when the car is not in use.7

In the drawings,Figure l is a vertical crosssection of the apparatus,and Fig. 2 is a vertical section longitudinally through the inclosingbox. In Fig. 1 the fire-pot is shown without the basket. 1

The fire-pot A is usually conical except at the bottom 2, which isadvantageously made square,with a lip 3 to retain the movable ashdrawerB, which sits in behind such lip, so as to be retained by the same andlessen the risk of the drawer falling out, and there is an opening 20for the admission of atmospheric air between the top of the ash-drawerand the lower edge of the fire-pot, at the opening through which 'such'ash-drawer is inserted, and there are also holes 4 through the sheetmetal of the fire-pot at the lower portion of the fire-chamber.

The basket 0 is preferably of wire and of a shape corresponding to theinterior of the fire-pot, and there is'a cross-bar or handle 0, by whichthe basket can be lifted out or replaced, and the stopper or cover Dfits closely into the fire-pot above the basket 0, so as effectually toprevent the escape of gases.

j The men is'of sheet metal, surrounding the fire-pot A and at asufficient distance from the same for, the atmosphere to circulatefreely between the fire-pot and the case, such atmosphere being admittedat the bottom through openings at land rising in consey que ncefof theaction: of the heat and passing 'out'at the top end of the case E andbelow the top F of the box F, which box has openings 6, preferablythrough the end portions, for the escape of the heated air into the car,and the top of the fire-pot A passes through the top F of the box F, andthe parts are secured together at this place, and there is a cover orlid G applied at this point to form an additional closure to the upperend of the fire-pot, and this ,lid may be hinged, and it can be openedor closed down, and at the bottom of the box F there is a ring or skirt8, passing through an opening in the bottom of the car, and this ring orskirt is a continuation of the case E, and the lower end of the fire-potalso passes through the bottom of the car and projects lower down thanthe bottom of the ring or skirt, and the cylindrical shield 15 surroundsthe lower part of the fire-pot near the hole 4:-

It is advantageous to apply this heater beneath the car-seat and eitherin the middle portion of the car or toward one or both ends, and overthe heater a part of the seat is made removable as a sectionsutficiently large to give access freely to the cover or lid G, and thisportion ll of the seat can be hinged in position, so as to be turneddown for completing the seat of the car and thereby not lessening theseating capacity. It is now to be understood that the seat H is raised,the cover or lid G removed, the stopper D lifted out, and fuel insertedinto the basket 0, and this may be ignited in any suitable manner. lVehave represented a torch I, of asbestos or other equivalent refractorymaterial, contained within an open-work casing and of a size adapted tobeing placed in the ash-drawer B, and this torch may be saturated withalcohol, benzin, or similar material, and the same is ignited to setfire to the fuel within the open-work basket 0. The stopper D is nowplaced into the conical fire-pot above the basket and the cover or lid Gshut down to place, so as to make the top part of the fire-chamberair-tight and prevent the escape of any gases or products of combustion,and there is suflicient air passing into the fire-pot through the holes4: and above the ash'drawer for maintaining the fuel in combustion, andany products of combustion may escape downward from the fire-pot, so asnot to pass into the car, and the heat of the fire-pot is given off tothe atmospheric air, which circulates upward between the case E and theexterior of the fire-pot, and such heated air passes into the box F andaway by the opening 6 into the car to warm the same. In this manner thecar can be easily heated, and sufficient fuel can be put into the basketat one time to remain in combustion during the time that the car ismaking a trip of ordinary length, and when desired the cover G can belifted and the stopper D removed for the insertion of fresh fuel or forthe withdrawal of the basket and its contents when the car is'put out ofuse at night, and we find that with fuel of the character mentionedthere is not any smoke, and the gases that may be generated do notescape into the car.

If desired, the cover G and the stopper D can bc'connected, as shown, soas to be moved together.

The front and back part of the box may be provided with a lining ofasbestos cloth or similar material, as at 10, and there may also be asimilar lining on the bottom and top, as at 11, so as to prevent theradiation or conduction of heat by the metal of the box.

Any hot air above the stopper D may pass out into the box throughopenings 12 in the upper part of the fire-pot.

e are aware that ear-heaters have in some instances been placed beneaththe car-seat, as in Patent No. 511,961, and that air has been admittedto pass around the heater and up into the car.

In our present invention the skirts below the bottom of the box F andpassing through the floor of the ear effectually protects the woodworkof the car from injury by the heat, and the shield 15 within the skirt 8and extending down farther lessens the risk of any gases or smell ofburning fuel passing into the car, because all such materials areconfined within the fire-pot and the shield and will be passed away tothe external atmos phere without the risk of such materials passing upwith the currents of air outside the shield 15 and within the skirt 8.It is also apparent that the case E within the box ll aids in heatingthe air by keeping such air closely in contact with the exterior of thefirechamber. In consequence of the stopper D fitting the fire-pottightly and there being an air-space between the top of this stopper Dand the cover G said cover is not liable to become heated, and theescape of products of combustion into the car is effectually preventedby the stopper D, and the circulation of air through the holes 12prevents the lid Gbecomingheated by radiation. These parts actingtogether insure the passage of the heat into the car without admixtureof deleterious gases, and there being no escape-flue to this heatingapparatus, there is nothing in the car to occupy space or to detractfrom the general appearance of such car.

We claim as our invention 1. The combination with the air-box having anopening at the bottom for admitting air, of a fire-pot withtightly-fitting covers at the upper end and air-inlets at the lower end,the lower end of such fire-pot projecting below the bottom of the car,and a shield 15 surrounding the fire-pot and closely connected to thesame at the upper end to prevent any gases passing into the air-box,substantially as specified.
